Mirayiridzo yekuvaka uye kushandiswa kweiyo lining zvinhu zvechoto chekupinza

The lining zvinhu zvechoto chekupinza chinhu chakaoma chakagadzirwa necorundum, hupfu hwakatsetseka, uye chromium oxide yegirini. Nzvimbo yekuvaka yezvigadziro zvehuni ye induction yakasiyana, uye nzira yekuvaka inoshandurwawo zvishoma.

Kana iyo lining material ye induction furnace yakavharwa pazasi pechoto, ukobvu hwemachira epazasi pechoto chekupinza 280mm, iyo inofanirwa kuzadzwa muna 4 nguva. Paunenge uchirovera nemaoko, zvinodikanwa kudzivirira kusaenzana kwese kwese. Nokudaro, jira revira rekupinza rinofanira kunyatsodzorwa. Ukobvu hwechinhu chacho kazhinji hahupfuuri 100mm nguva yega yega kana simbi yesimbi yekupinza yakavharwa, uye ukobvu hwemadziro evira hunodzorwa mukati me60mm. Iyo yekushongedza yevira yekupinza inofanirwa kutenderedzwa zvishoma nezvishoma ichitenderedza muchoto uye simba rakafanana.

Kana iyo lining material yechoto chekupinza yakavharwa pazasi pechoto kuti isvike pahurefu hunodiwa, inoda kupepetwa isati yaiswa mold yecrucible. Iyo crucible mold yakatarisana nemhete yekupinza, yakagadziridzwa yakatwasuka kumusoro uye pasi kuti inyatso batanidza nepasi pechoto chakavakwa, uye wozogadzirisa gap reparipheral kuti rienzane, risungirire nedanda rehuni, uye wodzvanya uremu hwepakati hwekusimudza kuti kudzivirira iyo induction choto lining material kubva pakuomeswa kana madziro echoto akavharwa Iyo formula material inobviswa.

Kana iyo yekubikira yevira yekupinza yakafukidzwa pamadziro echoto, ukobvu hwechigadziko chechoto chekupinza chiri 110-120mm, uye machira echoto chekupinza anofanirwa kuwedzerwa mumabhechi, uye jira rakafanana uye. panguva imwe. Ukobvu hwechigadziko chebira re induction hachipfuuri 60 mm nguva imwe neimwe. , Kusvikira yave kupeperetswa nekumusoro kwekumusoro kweiyo induction loop. Mushure mokunge knotting yapera, crucible mold haifaniri kutorwa kunze, kuitira kuti iyo yakagadzika yevheni yekupinza inogona kuita induction heat panguva yekuomesa uye kunyura.

Kubika uye sintering process yakakamurwa kuita nhanho mbiri. Nenzira iyi, iyo dense bonding chimiro cheiyo lining material ye induction furnace yakasimba.

Danho rekutanga rekugadzira furnace lining material kubika: kupisa kusvika 100 ° C pamwero we50 ° C / h, kubata kwe2h, kupisa pamwero we100 ° C / h kusvika 300 ° C, kubata kwe2h, chinangwa. ndiko kubvisa zvachose mwando muchoto chemoto.

Chikamu chechipiri chekupisa simbi yevira rekupinza: kupisa pa200 ℃/h kusvika 900 ℃, kubata kwe2h, kupisa pa100 ℃/h kusvika 1200 ℃, kubata kwe2h, choto chekutanga chesimbi yakanyungudutswa pa1400- 1650 ° C, kubata kweawa 1, kudzora Mwero wekupisa unodzivirira kuputika.
